How To Repair DC Voltmeter
Ғылым және технология
Hello friends in this video we will see how we can repair digital voltmeter. It has a voltage regulator which is usually 5v or 3.3v. Most of the time it is the voltage regulator that goes bad, so replacing it can fix the voltmeter.

Mr. Tariq Lab. Thanks for your video and information. As far as I know, and generally in such devices, the supply voltage is 3.3 volts and an smd regulator such as a 3.3 volt voltage regulator (for example AMS1117 3.3V) is used to provide this. Again in general this component is broken. Is it the 78L05 you are replacing, or any 3,3 volt regulator. Respects.
